From the foregoing description, it Will be obvious that We have provided an evener for the four sections of the harrow, Which, when in the position shown in Fig/l, Will serve to pull all of the harroW sections when a pulling force is exerted on the ring 38. Due to the hinge connection of the members 2O and 22, the bars 24 and the harroW sections C may be raised to an inclined position, as illustrated in Fig. 3. For maintaining' the end sections C in this position, we provide prop members 40. These members may be made of flat or channel-shaped bars depending on the strength desired and are substantially U- shaped in formation. The ends of the tivo arms of the prop members 40 are formed into eyes 42 for the purpose of a pivot connection.

Secured to the central fore and aft connecting bars 44 of the barrow bracket members 46. provided with eyes 48 and bolts 50 extending through these eyes and through the eyes 42 of the prop members 40, whereby a pivotal connection is provided. The brackets 46 are secured to the bars 44 by means of clamping bolts 52 and bars 54, as best illustrated in Fig'. 4. Normally, the prop members 40 lie in supine position upon the central harroiv sections B, as illustrated in Fig. l andas shown in dotted lines in Fig. 3.

When it is desirable 'to partially fold the end sections C for driving through a gate opening, the operator grasps the outer end of one of the sections C and raises it to the position shown in Fig. 3. During this operation he also raises the prop member 40 so that it may engage beneath the central fore and aft connecting bar 56 of the end section C.

When in this position, it is desirable to support the lower rear corners of the end sections C so that they will not drag on the ground. In order to do this, We provide fork members 58 secured to the rearmost bar 60 of the end harroiv sections C. These fork members when the harroiv is partially folded, engage over the rearmost of the bars 62 of the central harroW sections B, as clearly illustrated in Figs. 3 and 6. I

From the foregoing description of our invention, it will be apparent that ive have provided a folding evener with means in connection with the harrow sections for holding the end sections in partially folded position and supporting them with respect to the central sections of the harrovv.

It is, of course, obvious that some changes may be made in the construction and arrangement of the parts of our device whereby it .may be made for use in connection with three or five section harrows Without departing from the real spirit and purpose of our invention.- It can, in fact, be designed for any number of sections Where it is desirable to sections B areV These members arel fold the end sections over and it is our intention to cover by our claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably included Within their scope.

`We claim as our invention:

l. For use With a folding harroW evener, a plurality of haroW sections, means on one of the partially folded sections for holding another of the sections in position, said means comprising a prop member adapted to engage beneath one of the fore and aft connector bars of such other section whereby said last mentioned bar is retained thereagainst by gravity. n

2. For use with a 'folding harrow evener, a plurality of. harroW sections, means on one of the sections for holding another of the sections in partially folded position, said ymeans comprising a prop member pivotally mounted andadapted when in operative'position to engage beneathone of the fore and aft connector bars of such otherharrovv lsection whereby saidV last mentioned bar is retained thereagainst'by gravity and When in inoperative position to lie in a'supine position.Y i V i 3. For use With a harrow plurality or harrow sections, an inverted U shaped prop member connected to one of the narrow sections for holding another of the sections in raised positionrelative thereto when the evener is moved to folded posievener and a tion, said prop member being pivotally mounted and adapted when in operative position to engage against a frame bar of such other section throughout a substantial portion of the length thereof and when in inoperative position to lie in a supine position.

4. A folding harrow prop structure comprising a pair of brackets adapted to be secured to a fore and aft connecting bar of a barrow section and a prop member of inverted U sh. pe having the free ends of its arms pivoted to said brackets.

5. A folding harrow prop structure comprising a pair of brackets, means for clamping' said brackets in spaced relation to a fore and aft connecting bar of a harroW section and a prop member having a pair of arms and a cross bar and having Vthe free ends of its arms pivoted to said brackets.

6. For use With a hinged harroW evener and a plurality of harroW sections connected therewith, a prop member on one of the'harroiv sections for holding an end section in' raised position relative thereto When the evener is moved to folded position, said prop member being substantially of inverted U shape with its two ends connecte-d to one harroW section and its center engaging said end section when holding it in such raised position.

7. For use With plurality of harrovv a harroW evenerv and a sections connected thereto and some of the sections provided'at their rear corners with forked connecting and supporting means, a prop member comprising.' a horizontal center portion andarms extend.- ing at right angles @from the ends thereof,

t the ends ofsaid arms being pyotally conneeted to one of the harrow sections for holding'another ofthe sections in raised position relative thereto when the eveneris moved to folded position( Des Moines, Iowa, April 21,- 1928.' v
